Facility Comment / Recommendationi

The question contains no right answer.|

l The safeguards sequence logic diagram (Attachment 1) shows that the emergency 1

| generator G01 start signal comes from either a Unit 1 or Unit 2 train "A" '

safety injection signal.

The train "A" start signal to diesel generator G01 is via slave relays ISI-10X(2SI-10X) and ISI-14X (2SI-14X) (Attachment 2). These slave relays areactuated by master relay ISIA-A (2SIA-A) for automatic safety injectionsignals and ISIM-A (2SIM-A) for the manual safety injection signal. Both the ,

master and slave relays mentioned require 125 Vdc train "A" safeguards power |

| from Unit 1 (Unit 2) to actuate (Attachment 2).

Unit 1 train "A" safeguards protection cabinets 10156 and 10157 receive powerfrom panel D17, breaker 12. Panel D17 receives power from Dll, breaker 29 l(Attachments 3, 4, 5). 1

Unit 2 train "A" safeguards protection cabinets 2C156 and 2C157 receive powerfrom panel D22, breaker 3. Panel D22 receives power from Dll, breaker 32(Attachments 3, 4, 6). |

EPIP 1.1, step 3b, Rev. 18, pg. 4K/A 194001All6 (3.1/4.4)Facility Comment / Recommendation

The question is at an SR0 knowledge level at Point Beach Nuclear Plant. It isabove the knowledge level expected of an RO per the PBNP job and taskanalysis.

Notification of offsite agencies is the responsibility of the duty shiftsuperintendent and the technical support center. An R0 does not haveresponsibility for notifications in accordance with EPIP 2.1, " State andCounty Agency Notification." At Point Beach Nuclear Plant, theresponsibilities for notifications rests upon the security shiftcommander / designated offsite communicator and the emergency support manager asstated on Page 6 of EPIP 2.1.

Delete from the R0 exam.

NRC Resolution

Comment accepted. At the time of validation this question was believed to bevalid based upon a review of the facility's training material and learningobjectives for an R0. However, the NRC examiners determined upon furtherreview that all four answers could be interpreted as correct. Therefore, this iquestion has been deleted from the R0 and SR0 exams and was not considered inthe grading of either exam. !

The fire protection jockey pump just automatically secured following fillingof the accumulator tank to 130 psig when the relief valve on the accumulatortank lifts (setpoint is 150 psig). Air and system pressure drop to 90 psigbefore a local operator reseats the valve. What is the status of the fireprotection system at this time?

K/A 086000K402 (3.0/3.4) |

Facility Comment / Recommendation i

Answers "b" and "d" are correct.

The question states that the jockey pump just automatically secured following i

filling of the accumulator tank to 130 psig. For the jockey pump to have jstarted, the "ER" relay would have to be deenergized (see Attachment 1). The '

question states that the pump secured on pressurizing the accumulator to 130psig, thus contacts "MS-B" and "MS-A" are open, while the "ER" contacts are asshown since the "ER" relay is still deenergized (jockey pump secured onpressure, not level). With the "ER" relay deenergized, the air compressor,

' cannot be started and the jockey pump will be enabled to start on a decreasingpressure of 120 psig. The question then states that air and system pressure

.

drop to 90 psig which would cause the "MS-B" and "MS-A" contacts to close and|start the jockey pump and the motor driven fire pump would start on a lowsystem pressure of 95 psig as sensed by PS-3716 (see Attachment 2). Under theconditions given, the jockey pump would be running, the motor driven fire pumpwould be running, and the air compressor would be stopped which matches answer"b".

.

Because the question did not state the level in the accumulator, based on thecandidate's assumption, "d" may also be correct. The level difference between i

the short and long probe is 11 inches which takes less than one minute tochange using the jockey pump. With ti.- air leak at the top of theaccumulator, the jockey and electric fire pump would be running at 90 psig.By the time the operator takes action, level would be at the short probe.With level at the short probe, the "ER" relay is energized opening the j

contacts in line with "HS-A" and closing the ER contact in line with "R1" and i

"R2". Since the jockey pump was originally running, it wculd now secure dueto relay "R2" energizing and opening the "R2" contact in link with relay "Rl".this would result in the jockey pump being off, the electric fire pump on, andthe air compressor on resulting in "d" being a correct answer.

Because it is not clear in the question where the water level is during thisevolution, either "b" or "d" is correct depending on the candidate'sassumption.

Both "b" and "d" should be acceptable.

NRC Resolution

Comment accepted. However, changes to the answer choices were recommended bythe facility during the examination review and subsequently incorporated intothe examination. The answer key has been changed to reflect either "b" or "d"as a correct answer. Credit was given for either "b" or "d" when thisquestion was graded.

With no CCW pumps running per A0P-98, Step 7.3.1, letdown would be securedmaking "a" the correct answer. Then when the VCT high temperature alarm isreceived, per A0P-9B, Step 7.3.4, the ope-ator would be required to shiftcharging pumps to the RWST making "d" also correct.

Both "a" and "d" should be acceptable.

a. reposition to open the dump valves and the dump valves dump steam

b. do not reposition but the dump valves modulate open and dump steam

c. reposition to open the dump valves but the dump valves do not open

d. do not reposition and the dump valves do not open

TRHB 13.9, 2.1, 2.2, Rev. 1LP0253, 3.3.3, Rev. 3K/A 016000K303 (3.0/3.1)

Facility Comment / Recommendation

Answers "c" and "d" are both correct.

The sentence "...the steam dump solenoid valves (SV-2050B-2057B) for the |positioner air signals..." refers to two separate components in the steam dump I

system.

SV-20508 - 2057B are " ARMING" solenoids in series with the air operatedpositioner valves (see Attachment 1). These valves open when a load reductionof 10% within 120 seconds is sensed from turbine first stage pressure(PT-486). Their operation is not affected by auctioneered Tavg. Thesesolenoid valves "do not reposition and the dump valves do not open" upon afailure of Tc 401B making "d" a correct answer. ;

6

_.

i,

1

The oositioner is the valve which controls the modulation of the condensersteam dumps (Attachment 1). With no turbine trip signal present, auctioneered '

Tavg is compared with the reference temperature (based on turbine impulse i

pressure, PT-485) and a modulation signal is sent to the positioner (seeAttachment 2). A failure of Tc 401B high would be sensed as increasing

,

auctioneered Tavg and would cause the positioner to " reposition to open the )dump valves but the dump valves do not open" making "c" a correct answer also.

1The way the question is written, some students felt it was asking for theresponse of the positioner, while others felt it was asking for the response ,

of the solenoid valves themselves. This does not represent a misunderstanding I

of how the system operates, but, a misunderstanding of the question. Because jof this, both answers "c" and "d" should be accepted. j

Both "c" and "d" should be acceptable.

NRC Resolution !

I Concur with the facility comment regarding the ambiguous and confusing wording |of the question. Note that the examination proctors received no requests for |

clarification of this question from the applicants. Upon further NRC review, |examiners determined that this question does not meet the guidelines jestablished in NUREG-1021, Rev. 7, Operator Licensing Examiner Standards, and i

NUREG/BR-0122, Rev. 5, Examiners' Handbook for Developing Operator Licensing jWritten Examinations. This question has been deleted from the R0 and SR0 |exams and was not considered in the grading of either exam.
